Application filed ul 19,1926. Serial No. 123,470;

My invention relates to ship. governors and action of the ship and not affected by the vibrations thereof. a Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate similar parts, p Figurel'is a side elevation of a governor withfpa'rts' broken away for clearness of illustration, 7

Figure 3, a section'onthe line 3 3 of F g ure 1, and

Figure 4, asection on the lined-4: of Figure'Lx'. 3 1 1,

In the drawings the numeral 10, denotes a base block rigidly secured to the hull of the ship at a point between the boilers and engine thereof. An upright 11 is secured to the base block and stands upwardsand is ata section on theiline 2-2 of :Fig-

tached to the stem pipe 12, which feeds steam.

to the engines. A shaft 13 extends through the upright. 11 and pipe 12 and carries a disk valve 14 on the end in the pipe 12 while a segment 15 is secured adjacent the opposite end. The segment 15 meshes with a larger segment 16 on the upper end of a pen-' dulum arm 17 mounted to swing on a shaft 18 supported by the upright 11. I The lower end of the pendulum carries a bracket 19 which, with the arm 17, forms a fork. The arm 17 and bracket 19 are slotted as at 20 to receive a shaft 21 upon which is mounted the pendulum weight composed of a heavy 'wheel'22 adapted to rotate between the bracket 19 and arm 17 and a pair of grooved guide rollers 23 which roll on tracks 24 secured to or formed integral withthe base 11. A pair of retaining guide rails 25mounted to lie in'the upper portion of the grooves in the rollers 23 to prevent the displacement of the wheel 22. I I

.Adjaceiiti bnei end-of the tracks is a spring bumper-26 mounted in a fixed stainlard 27 secured 'tothe base 10, while at the oppositefend is a similarbumper 28 mounted in an"adju.stable bracket 29 adapted to slide in a pair ofguideways 30 and adjusted bymeans of a screw 31 and hand wheel or crank 32. -The'adjustment of the bumper 28 governs'the position of the valve 14 when it is closed by the pendulun'r After the ship has been loaded with cargo it is necessary to trim oralign the device so that the f tracks 24 are perfectly horizontal. This isaccomphshedby mounting the base block 10 on fulerums83 projecting upward from the-keel of the shipso that the angle of incidence between the block and ship may bechanged. The block 10 carries a bracket 1 7 34C thread-ed to r-eceivea jack-screw 35 which is swivelled intov the. keel; Turning the screw 35 in one dlrection'will raise the'cor responding end of-the block 10 whilethe op? vposite direction will lower-the end of the block.

The operation of the device is as follows: VVhenthe shipjis ridingon an even keel the pendulumshangs-in the normal position shown. at N inFigure 1, and the valve 1 1 is open permitting full steam to pass. Upon encountering a rough sea the bow of the vessel tllts downward which causes the stern to raise and in some instances carrying the propellers out of the sea; causing themto 7 race, but the tilting of the ship causes the wheel 22 to roll towards the bumper-28 car- A rying with it the pendulum arm 17 which steam to the engines, thereby checking theirspeed. The wheel 22 remains in the forward.

position until the bow has raised slightly above the even keel position when the wheel 22 gradually rolls backward against the bumper26, thereby permitting full steam to enter the engines again. The design of pen-; dulum described does-not maintain a con stant perpendicular position that would exist v w1th a pendulum having a fixed weight atthrough the segments cuts off a portion of the y tached thereto, but instead the arm 17 is carried out of the perpendicularposition by means of the travel of the wheel 22 on. the I straight tracks 24. This construction causes a positive movement of the pendulum governed by the inclination of the-tracks 24 and not by the jolting of the ship. v i

It will be obvious to those skilled in'the art that various changes may be made in my device without departing from the spirit of the invention, and Ltherefore, do not limit myself to what is shown in the drawings and described in the specificatiombut only as indicated in the appended claims.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:

1. A governor comprising a pendulum arm, a steam valve controlled by the fulcrum end thereof, a rotating weight j ournalled in slots in the lower end thereof, guide rollers rotating with said weight'and straight guide rails for said rollers, substantially as set forth.

2. A governor comprising a pendulum arm, a steam valve icontrolled by the fulcrum end thereof, a rotating weight journalled in slots in the lower end thereof, guide roller-s rotating with said weight, straight guide rails for said rollers to roll upon, parallel retaining rails-for said rollers and bumpers for limiting the travel-of said rollers and Weight, substantially as set forth.

3. A governor compri'singa pendulum arm, a steam valve controlled by the fulcrum end thereof,' a rotating weight journalled in slots in the lower end thereof, guide rollers rotating with said Weight, straight guide rails for said rollers to roll upon, parallel retaining rails for said rollers and adjustable means to govern the degree 7 of movement of the steam valve, substantia'll'y as set forth. 1

4. A governor comprising a pendulum arm, a steam valve controlled by the fulcrum end thereof, a rotating weight jourparallel retaining rails for said rollers and adjustable means to govern the degree of movement of the steam valve comprislng a bumper, an adjustable bracket for said bumper, and means for changing the adjustment thereof, substantially as set forth.

5. A ships governor comprising a pendulum arm, asteam valve controlled by the fulcrum end thereof, a rotating weight journaled in slots in the lower end thereof, guide rollers rotating with said weight, straight guide rails for said rollers to roll upon, a block for supporting the above structure, and means for adjusting the alignment of said block with the position of the ship, substantially as set forth.

6. A ships governor comprising a pendu' lum arm, a steam valve controlled by the fulcrum end thereof, a rotating weight journaled in slots in the lower end thereof, guide rollers rotating with said weight, straight guide rails for said rollers to roll upon, a block for supporting the above structure, and means for adjusting the alignment of said block with the position of the ship, comprising a fulcrum between said block and said ship, and a jack screw carried by said block and swiveled into said ship, substam tially as set forth.

In witness whereof, I have hereunto set my hand at Oakland, California, this 28th day of June, A. D. nineteen hundred and twenty-six.
